| Abstract | Two kinds of peony roots--white peony root (WPR) and red peony root (RPR)--are used for different remedies in traditional Chinese medicine; however, most of them are derived from the same botanical origin, Paeonia lactiflora. The difference between WPR and RPR has been debated for a long time. This study attempted to clarify the genetic and chemical characteristics of WPR and RPR in order to provide a scientific dataset for their identification and effective use. The nucleotide sequence of nrDNA internal transcribed spacer (ITS) and the contents of 8 main bioactive constituents were analyzed from specimens of P. lactiflora, P. veitchii and two related species as well as crude drug samples of WPR, RPR and peony root produced in Japan. Of the samples derived from P. lactiflora, the WPR produced in the southern parts of China and the RPR produced in the northern parts of China were clearly divided into two subgroups within the P. lactiflora group based on similarity of the ITS sequences. The nucleotides at positions 69, 458 and 523 upstream of the ITS sequence served as molecular markers to discriminate between WPR and RPR. Quantitative analysis indicated that the RPR samples obviously contained a higher content of paeoniflorin and paeonol, but a lower content of albiflorin than the WPR produced in the southern parts of China and peony root produced in Japan. The WPR available from Chinese markets was usually processed by sulfur fumigation, which resulted in an extremely low content of paeoniflorin. This study indicated that WPR and RPR were not only geographically isolated, but also genetically and chemically separated. The ITS sequence provided a genetic index for their identification. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
